FLASK FOR FouNDR Es.

SPECIFICATION forming part of Letters Patent No. 763,465, dated June 28,1904.

Application filed August 8, 1903.

To all whom, it may concern:

Be it known that I, EDWARD J AMES CoeH- RAN, a citizen of the UnitedStates, residing at Sterling, in the county of Whiteside and State ofIllinois, have invented certain new and useful Improvements in Flasksfor Foundries; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters and figuresof reference marked thereon, which form a part of this specification.

My invention has reference to foundry flasks or molds, and relates moreparticularly to devices of that class for casting heads on the pintlesof door-hinges, the chief features and advantages of which will be morefully. set forth in the following specification.

In the manufacture of hinges the pintles are in some cases constructedof steel or other metal possessing similar qualities capable of enduringthe strain which comes upon this part of the hinge. The heads are thencast thereon, being formed of a softer metal.

In the drawings, Figure 1 is a plan view of my device. Fig. 2 is a frontelevation thereof with one of the halves of the flask removed. Fig. 3 isan end elevation of my device. Fig. 4 shows a pintle such-as is used inhinges with a head formed thereon. Fig. 5 is a detail similar to Fig. 2,showing a modified form of mold. Fig. 6 shows a metal ornament forhinges cast in the mold shown in Fig. 5.

Similar numbers and letters refer to similar parts throughout theseveral views.

-The flask consists, primarily, of two metal parts 1 and 2, the part 1being provided with perforated ears 3 3 and the part 2 with two pair ofperforated projections i 4. By means of pins 5 such ears and projectionsare detachably secured together and the inner faces of the parts 1 and 2held in contact. Projected from the ends of the part 1 are trunnions 6,suitably supported on a frame 7, so as to permit the flask to beinverted.

Referring to Fig. 2, the numerals 8 represent a series of molds ofsuitable form having Serial No. 168,697. (No model.)

' circular openings 8, extending to the lower face of the part 1. Bymeans of funnel-shaped channels 9 the several molds communicate withadepression 10 in the upper face of the flask. The part 2 is similarlyprovided with molds 8, openings 8, channels 9, and depression 10, whichseverally correspond with the like parts in the part 1 and complete themold. Secured at the ends of the part 1 by screws a a is a swingingU-shaped frame 11, upon which the pintles are supported While theoperation of casting the heads thereon is proceeding. By means of two ormore holes 12 in the legs of the frame 11 such frame is capable ofvertical adjustment to accommodate pintles of different lengths.

In Fig. 4: is shown a pintle 13, upon Which has been cast the head 14 inthe manner herein described. I

Fig. 5 illustrates one half of a flask, in which the lower ends'of theopenings 8 are closed. By this construction are produced the ornamentalknobs 15, Fig. 5, which are inserted in the lower end of the hinge atthe end of the pintle in inverted position to complete the hinge.

In operation the flask is inverted with the parts secured together andthe frame 11 turned to one side. The pintles 13 are then inserted intothe openings 8 to a point a little beyond the position they occupy Whilethe heads are being cast thereon. The frame 11 is then returned to itsformer position, the supporting part thereof being just above the endsof the pintles. The flask is then turned to its original position, as inFig. 2, the pintles dropping downwardly until they rest upon the support11. The ends of the pintles then project a desired distance into themolds 8.

- insertion of the pintles, removing any possible moisture which mightbe thereon.

Any desired number of sets of the castings can be successively producedby the use of the mold, the artificial heating of the flask beingnecessary before the casting of the first set only. 7

What I claim as my invention, and desire to secure by Letters Patent ofthe United States,

The combination in a flask for the purpose specified, of the parts 1,and 2, removably secured to one another, molds, 8, centrally of saidflasks, passages 8 communicating therewith, an integral U-shaped framehaving its legs formed with a plurality of holes, and screws passingthrough said holes and engaging in said flask whereby said frame ishingeably and adjustably secured with respect to said flask.

In testimony whereof I aflix my signature in presence of two witnesses.

EDWARD J. COCHRAN.
